Novel HMW glutenin genes from Aegilops tauschii and their unique structures
Wen-Jie Chen,Zhong-Wei Yuan,Lian-Quan Zhang,Xing Fan,Ze-Hong Yan,Ji-Rui Wang,You-Liang Zheng,Huai-Gang Zhang,Deng-Cai Liu 한국유전학회 2012 Genes & Genomics Vol.34 No.3
A pair of novel high-molecular-weight glutenin subunits (HMW-GS) 1Dx5.3t and 1Dy12.1**t were revealed and characterized from Ae. tauschii accession PI554324. SDS-PAGE band of 1Dx5.3t was between those of 1Bx6 and 1Bx7, while 1Dy12.1**t with slightly faster migration rate than that of 1Dy12. The lengths of 1Dx5.3t and 1Dy12.1**t were 2115 bp and 1986 bp, encoding 703 and 660 amino acid residues,respectively. Their authenticity was confirmed by successful expression of the coding regions in Escherichia coli. 1Dx5.3t is the shortest of the known Dx-type alleles. 1Dy12.1**t is also a special subunit since it has an additional cysteine in the front of the central repetitive domain. This cysteine that is not existed in previously reported Dy-type genes may be useful for improving bread wheat quality. Median-joining Network analysis indicated that 1Dy12.1**t may be a key site in the genealogy of the Glu-Dy.

A about 2-month- old, mixed female cat was refered to Yeon Chang Veterinary Clinic in Taiwan. Becausethis patient was wandering cat, precise history was not known. At first admision, miosis, ptosis and protrusion of the nictitating membrane was observed in the right sided eye, and also slight miosis was found in the left sided eye. The patient was diagnosed into feline HS. Oculo-AP and injection-AP with dexamethasone were applied to this patient. minutes. In addition, injection-AP with dexamethasone (0.2 ml/acupoint) at BL01-Jing Ming, BL02-Zan Zhu and ST01-Cheng Qi. After AP treatment, prolapse of the nictitating membrane was amazingly disapeared and pupil was dilatated at sesion 1. Ocular findings at sesion 2 (one day after sesion 1) were maintained with nearly normal state. Accordingly, the present patient was a case with feline HS that showed favorable therapeutic effect by AP treatment.

The aim of this paper is to design a centrifugal deformation error compensation method with guaranteed performance that allows angular velocity measurement of the magnetically suspended sensitive gyroscopes (MSSGs). The angular velocity measurement principle and the structure of the MSSG are described, and the analytical model of errors caused by MSSG rotor centrifugal deformation is established. Then, an on-line rotor centrifugal deformation error compensation method based on measurement of rotor spinning speed in real-time has been designed. The common issues caused by centrifugal deformation of spinning rotors can be effectively resolved by the proposed method. Comparative experimental results before and after compensation demonstrate the validity and superiority of the error compensation method.
Modeling and Analysis of Drift Error from Stator of A MSSG with Double Spherical Envelope Surfaces
Chao-Jun Xin,Yuan-Wen Cai,Yuan Ren,Ya-Hong Fan 대한전기학회 2016 Journal of Electrical Engineering & Technology Vol.11 No.5
For the newly developing magnetically suspended sensitive gyroscope (MSSG) with double spherical envelope surfaces, it is necessary to analyze the causes of drift error to improve sensing accuracy. This paper builds the models of disturbing torques generated by stator assembly and process errors based on the geometric construction and running regularity of the MSSG, and further reveals the generation mechanism of the drift error. Then the drift error from a single stator magnetic pole is calculated quantitatively with the established model, and the key factors producing the drift error are further discussed. It is proposed that the main approaches in reducing the drift error from stator are guaranteeing the rotor envelope surface to be an ideal spherical and improving the controlling precision of rotor displacement. The common problems associated in a gyroscope with a spherical rotor can be effectively resolved by the proposed method. This analysis provides a reference for the structure optimization and error compensation of a MSSG.

Four known lanostane triterpenoids, schiprolactone A (1), schisanlactone B (2), nigranoic acid (3) and schisandronic acid (4) Were isolated from the stems of Schisandra henryi for the first time. Their structures were characterized by IR, MS and NMR techniques. Compounds 1, 2 and 4 showed moderate cytotoxic activity against Leukemia cells in vitro. Cytotoxic activity of compounds 1-4 showed $IC_{50}$ of 0.0097, 0.01, 0.097 and 0.0099 $\mu$ mol/mL respectively toward Leukemia cells and $IC_{50}$ of 0.097, 0.1, 0.097 and 0.099 $\mu$mol/mL toward Hela cells respectively. It is the first report that these compounds possess cytotoxic activity on Leukemia and Hela cells.
